的结构，相图，和一个非常规的超导状态信号的中子共振的外观提供有关的铜酸盐，铁磷属元素化物和硫属元素化物以及一些重费米子和锕系元素材料的唯象证据。单带和多带Hubbard模型已经被发现可以描述这些材料的许多观测性质，因此可以合理地研究这些模型中配对相互作用的起源。本文基于实验现象学和Hubbard模型中对相互作用的研究，提出自旋涨落介导的对相互作用是联系广泛的一类超导材料的共同线索。
The structures, the phase diagrams, and the appearance of a neutron resonance signaling an unconventional superconducting state provide phenomenological evidence relating the cuprates, the Fe-pnictides and chalcogenides as well as some heavy-fermion and actinide materials. Single-band and multiband Hubbard models have been found to describe a number of the observed properties of these materials so that it is reasonable to examine the origin of the pairing interaction in these models. In this review, based on the experimental phenomenology and studies of the pairing interaction for Hubbard-like models, it is proposed that spin-fluctuation mediated pairing is the common thread linking a broad class of superconducting materials.
